*The [[Dobbertin Harddisc|Dobbertin HD20]] with [[Dobbertin Smart Watch]] is the true historical solution. But it's clumsy to use with 4 partitions of 5MB each and no FAT filesystem. While it clearly has historical value, is it still relevant to the community today?
*[[Symbiface II]] IDE/PATA mass-storage or [[X-Mass]] with [[Nova]] NVRAM/RTC is the historically-plausible solution as the IDE/PATA interface was created in 1986. But it's a lie as the IDE interface was effectively introduced on the CPC with the [[CPC-IDE]] prototype in 2004, and the Symbiface II being available in 2006. Also, these devices don't offer any network support.
*[[Symbiface 3]], [[Albireo]] and [[M4 Board]] are the modern solutions that feed the CPC a direct file view of the mass-storage instead of a sectors view. So the FAT filesystem does not need to be handled on the CPC itself. Which means there is no need for the [[Nova]] NVRAM to help handling the filesystem. It's overall a simpler, more convenient approach. And it is definitely more future-proof. But that means throwing away historical pretense.
*Symbiface 3 possess an onboard mp3 player. Are we still talking about Amstrad CPC here?
*Albireo provides low-level access to internet via SLIP which means having the IP stack on the CPC side instead of it being done by the peripheral like in the M4 board, and having a bridge server on the other side. So it is not convenient at all. Also, just like the X-Mass, the Albireo does not provide RTC functionality.
